The HSI (Horizontal Situation Indicator) is a backup for the HSD (Horizontal Situation Display) of the MFDs
and waypoints on the
HUD. The HIS provides information about course,
bearing, distance to
TACAN stations, navigation fix-points,
landingstrips, tankers or waypoints. This navigation aid is shown as "birdsview". The A/C is allways located
at the center. The bearings and positions are based on a 360° compass. The HSI together with the INSTR MODE Switch
on the
INSTR-Panel allow the selection of TACAN or NAV data.
This indicator is located in the middle of the
center console.
